Description

technical field [0001] The invention belongs to the technical fields of marine detection equipment, marine development and marine safety, and in particular relates to a deep-sea acoustic launching submersible. Background technique [0002] The submersible buoy has been widely used as an important marine survey equipment. The submersible buoy has good concealment, is not easy to be damaged, has a simple structure, is easy to deploy, has a high success rate of recovery, and can work underwater for a long time. Among them, acoustic submersible buoys are widely used in many fields such as marine survey, marine environment monitoring, underwater acoustic physics research, underwater acoustic communication, underwater positioning and navigation, and national marine security. [0003] The underwater acoustic launch submersible is a kind of underwater acoustic device placed in the sea that can actively transmit acoustic signals according to the set program.

Problems solved by technology

[0005] However, the traditional underwater acoustic launching submersibles mainly have the following two problems: First, the current launching submersibles generally have the problem of insufficient signal processing capability, and there are fewer types of transmitting signals, which are not easy to adjust, and do not have a signal source The ability of encoding and arbitrary signal generation is difficult to adapt to various needs in practical applications, and it does not have the feasibility of expanding applications

At the same time, the power consumption of the circuit used for signal processing and power amplification of the launching submersible is high, which seriously affects the underwater working time; the common method is to increase the scale of the energy battery pack, but this will increase the size and weight of the submersible and affect the endurance The design of the pressure structure is difficult, and it also increases the difficulty of laying and recovering the submersible tags. Therefore, the submersible tags need to reduce the power consumption of the system as much as possible under the premise of having a certain computing power.

Second, the traditional underwater acoustic launching submersibles are often restricted by energy conditions and working methods, and the range of action is small and the coverage is not enough. The first solution that comes to mind is to use multiple submersibles to work together. The collaboration ability between standards puts forward higher requirements. The most direct solution is to add two-way underwater acoustic communication equipment, but this will increase hardware overhead, increase system complexity, and bring a series of problems such as reliability and acoustic compatibility. technical problem
